1,923,285 BEVETPULLER. SHARE Frank N. Tonkinson, Longmont, 0010.Application January 9, 1932. Serial Nb. 585,769 3 Claims. (01. 55106)This invention relates to beet puller shares, and has for its object theproduction of a simple and efficient puller share, which is constructedwith a projecting or elongated narrow finger at the soil penetrating endfor the purpose of more efficient extracting the beets from thegroundand also for producing a durable and efficient share.

Another object of this invention is the produc- 0 tion of asimple andefficient reversible beet pull- 1 forcing the beet up between theconverging ends of the pair of shares which are adapted tobe usedtogether.

A still further object of this invention is the construction of a simpleand eiilcient beet pulling share which is simple in construction andcomprises a minimum number of parts.

ith these and other objects in view, this invention consists in certainnovel constructions and arrangements of parts which will be hereinafterfully described.

In the drawing:- 7

head shown in dotted lines and indicated by the numeral 3, and beingsecured by means of the fastening screws 4. I I

In carrying out the present invention, two shares as indicated ingeneral by the numeral 5 are employed, one share being supported uponeach arm 2, and the shares being so mounted upon the arms as to convergetoward their rear ends and to be pitched at an angle to suit theconvenicnce of the operator, preferably at an angle of approximatelyforty-five degrees pitch from the front to the rear of the shares.

Each share comprises an elongated body, as shown in the drawing, thebody 5 being provided ing share which is adapted to efiiciently open upthe soil and facilitate the pulling of the beet by employed withoutdeparting from the spirit of the along its inner edge and at eachend,with a projecting tapering finger 6, each finger being provided upon thetop thereof and at. its extremity with a cutting beveled point 7, andupon the bottom thereof with diverging beveled portions 8 and 9,terminating in a lower cutting edge 10, as clearly shown in the drawing.The finger 6, in

each instance, is preferably of an elongated narrow type and projectsfrom the body at one side of a cutting face or blade 11 having ashapened edge extending transversely across the end of the body 5diagonally from the finger. The body preferably extends substantiallyfiat throughout the. main portion of its length-but has its end portionsbowed rearwardiy to cause the finger 6 and biade 11 at its lower end toreadily enter the ground as the machine movesforwardly. In view of thisparticular structure the fingers of the two shares will enter the soilin advance of the blades 11 to form narrow trenches at opposite sides ofa row'of beets, after which the blades which are in set-back relation tothe fingers will slice their way with the laterally extending rearwardlyinclined blade 11, as described.

As shown in Figure 6, there is a modified form of the invention whereinthe body 12 of the share is provided with a finger v13 similar to thefinger 6, only at one end. In carrying out the'invention, 9O 7 the sharemay be constructed so as to provide a finger at both ends, or one end,of the share according to the desire of'the manufacturer or operator. Inthepreferred embodiment however, it is preferable to provide theprojecting fingers at each end of the share in order that the blades maybe reversed provided one end should become worn.

It should be understood that certain detail changes in the mechanicalconstruction may be invention so long as these changes fall within thescope of the appended claims.

Having described the invention, what is claimed as new is: I i

1. I eet pulling means comprising a frame including supporting elementsspaced transversely from each other, and shares carried by saidsupporting elements, said shares extending upwardly at a rearwardincline in converging relation towards their upper ends and each at itslower end wardly for the full Width of the share.

2. A beet'pulling share comprising an elongated metal plate having afinger projecting 1ongitudi' nally thereof from one end at a side of theplate and sharpened at its free end, the adjacent end of the plate beingstraight cut from the inner end of the finger to the other side edge ofthe plate and sharpened, said plate being flat for the major portion ofits length, and the finger and adjacent end portion of the plate beingbowed longitudinally to curve downwardly and rearwardly when the shareis mounted in position for use.

3. A beet pulling share comprising an elongated plate adapted to besecured intermediate its length to a support and extend upwardly at arearward incline, said plate having a finger extending from each endlongitudinally thereof at one side of the plate, ends of the platebetween the fingers and other side edge of the plate being straight outand extending diagonally in converging relation to each other to formblades spaced from the free ends of the fingers, the fingers andadjacentend portion of said plate being bowed longitudinally wherebywhen the share is mounted in position for use a selected end may bedisposed lowermost and have at its lower end a downwardly and rearwardlycurved blade and finger for progressively entering the ground.
